I have four different parts numbers

Hello,

At first glance, your operator looks a lot like our 39-031 or 39-155, depending on the length of the link arm. Upon closer inspection, the base and position of the handle is different. These are definitely our best replacement options but because of the difference in the base that you use to install it, you would most likely need to make adaptations for one of these to work for you, if it will work at all. Take a look and see if either of these could work for you. Thank you!
